Problem

Two horizontal springs with force constants

k_{1} = 300\,\text{N/m}

and

k_{2} = 600\,\text{N/m}

are connected in parallel to a rigid wall on one side and a block of mass

m = 2.25\,\text{kg}

on the other. The block rests on a frictionless horizontal table. Calculate the period of small oscillations if the block is displaced.
